Definitions

• the present patent application for industrial invention relates to a patient-supporting device.
• a patient is a person who is forced to lie on a bed because of a disease, injury or the like.
• the reference field is the sector of stretchers, wheelchairs and mobile patient-supporting devices in general, which are suitable for supporting and transporting a patient who is unable to walk.
• the invention addresses the problem of moving a patient from a bed to the supporting device and vice versa.
• the term“bed” refers to a bed of a house, a bed of a hospital or a surgical bed.
• Wheelchairs are used to move and support the patient in sitting position, whereas stretchers are used to move and support the patient in supine position.
• Wheelchairs are used on a daily basis for the transportation of a patient not only in a hospital setting, but also in a domestic environment.
• Wheelchairs have a compact structure and are very useful for moving patients around in narrow spaces.
• the patient is usually transferred from the bed to the wheelchair by health operators who manually lift the patient from the bed and place him or her on the wheelchair.
• stretchers are mainly used for transporting a patient from an operating room to a hospital room or vice versa.
• Stretchers are longer than wheelchairs and they are consequently difficult to use in narrow spaces.
• the transfer of a patient from the stretcher to the bed and from the bed to the stretcher is less complicated than the transfer from the bed to the wheelchair and from the wheelchair to the bed (because the patient remains in supine position), but is in any case impaired by drawbacks.
• the stretcher During the transfer from the bed to the stretcher or vice versa, the stretcher must be positioned next to the bed.
• the patient may fall down by gravity, partially hitting the bed and the stretcher.
• the impact of the patient on the stretcher may move the stretcher, making the patient fall on the ground.
• the purpose of the present invention is to overcome the drawbacks of the prior art by providing a patient-supporting device that is reliable, versatile and inexpensive.
• An additional purpose of the present invention is to disclose a supporting device that permits to transfer the patient from the bed to the supporting device and from the supporting device to the bed in an easy, safe way, without requiring an excessive physical effort for the operator and minimizing the possibility of serious injuries or damage for the patient.
• the supporting device comprises a right-hand side, a left-hand side, a front portion and a back portion.
• the supporting device also comprises a support frame suitable for resting on the ground, and an articulated frame suitable for supporting the patient.
• the articulated frame comprises a horizontal central portion suitable for supporting the patient’s pelvis, a front portion suitable for supporting the patient’s legs and a back portion suitable for supporting the patient’s chest; the front portion is disposed in correspondence of said front portion of the supporting device; said back portion is disposed in correspondence of the back portion of the supporting device.
